Logo Slider WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Logo Slider WordPress plugin, specifically in versions through 4.9.0. The issue arises from inadequate input sanitization and output escaping in the 'logo-slider' shortcode, allowing authenticated attackers with author-level access or higher to inject arbitrary scripts into pages. These scripts are executed when a user accesses the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
